Petrol with ethanol (“E” stands for Etha-
nol). The number indicates the percent-
age of ethanol in the petrol. “E5” means,
for example, an ethanol ratio of 5% max.
Diesel with biodiesel (“B” stands for Bio-
diesel). The number indicates the per-
1 2 centage of biodiesel in the diesel. “B7”
means, f

ample, a proportion of bio-
diesel of max. 7%.
Natural gas: “CNG” means Compressed
Natural Gas.
Type of petrol Applies to vehicles: with petrol engine
The corr ect gr
ade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10) 2)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
The following pieces of text show the infor-
mation included in the corresponding stickers
on the tank lid (examples): 3 Super unleaded petrol 95 octane petrol or

We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available: normal 91
octane petrol (87 AKI) (with a slight power
loss).
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least.
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
